The Cardev 4S350C12 bypass filter is suitable for a wide range of machinery, including mobile plant and industrial applications. The 4S350C12 is permanently installed using the integral mounting brackets. A pressurised feed (up to 350 Bar) is taken from a hydraulic circuit, and a return line (to tank) completes the bypass loop. A flow compensating, pressure reducing valve arrangement reduces the pressure in the filter housings to 4 Bar, and restricts the flow rate to 12 l/min.

For larger systems (capacity of 1000 litres +), and for systems that suffer from excessive contamination, the 6S350C16 is also available.
